Hi,

I think I did everything like advised, but the data query does not show up in the list. Therefore I can not create graphs.
I use 0.8.6i
Please help to find the error.

For some reason, I am only seeing the first 20 diskIODevice. Is this something with the Cacti frontend, or is it something with the query?

cacti-0.8.7a-1
CentOS 4.4

Thanks!

when I go to create a graph what do I put for index type, index value, and output type id?

I'm also having a hard time figuring out which ones are my fiber SAN luns. I think it's the ssd's because there is some ssds for the luns in the /devices/scsi_vhci? (I'm on Solaris).

Here's some (hopefully) helpful info.

Did anyone manage to get this working on any recent version of Cacti?

I followed the steps in the initial instructions, but can only manage to get "Bytes Read/Written" to work. I'm running on a FreeBSD 6.2 machine and I can successfully manage top pull the information with snmptable and snmpwalk

Almost everything is working great for the Disk I/O template with the exception of 2 of the 3 graphs, Device I/O Reads/Writes and Load Average. I did a debug output of the Read/Writes graph and noticed the
ERROR: the RRD does not contain an RRA matching the chosen CF
At the bottom, any ideas on how to fix that?

I have witnessed the same problem with 2 of the 3 graphs not working, and displaying the following error when you turn on graph debug mode:

ERROR: the RRD does not contain an RRA matching the chosen CF

I got these two other graphs to work by changing the graph template to use AVERAGE rather than LAST on the AREA and STACK components.

This issue is discussed at more depth here:

Hope this helps.
